<h3 id="rationale">Rationale:</h3>
<p>ShellCheck has no first class support for <code>ash</code>, but it
does support its Debian fork <code>dash</code> and defaults to this
whenever <code>ash</code> is specified.</p>
<p>Unfortunately, while the two are similar, they are not completely
compatible. For example, <code>ash</code> supports <code>echo -e</code>
but <code>dash</code> does not, so ShellCheck will incorrectly warn
about it.</p>
<p>You can use a <a href="directive.html">directive</a> to let ShellCheck
know you're aware of this problem.</p>
<h3 id="exceptions">Exceptions:</h3>
<p>None.</p>
